The Shure BLX24R/B58 Wireless Handheld Microphone System combines the professional vocal performance of the Shure BETA 58A supercardioid dynamic microphone with the convenience of Shure BLX analog UHF wireless technology. Featuring the BLX2/B58 handheld wireless transmitter and BLX4R single-channel rackmount receiver, this complete wireless microphone system is designed for live performances, houses of worship, touring sound systems, corporate AV, and professional audio installations.
The BETA 58A microphone capsule delivers focused vocal pickup, excellent off-axis sound rejection, and a tailored frequency response that helps lead vocals and spoken presentations remain clear in amplified environments. Its supercardioid pickup pattern makes it particularly useful for performers working near stage monitors, instruments, and other sound sources.
The included Shure BLX4R rackmount receiver offers convenient integration into professional equipment racks, with one-touch QuickScan frequency selection, RF and audio metering, and balanced XLR and 1/4-inch audio outputs.
With up to 300 feet (91 meters) of wireless operating range under suitable conditions and up to 14 hours of battery life using two AA batteries, the BLX24R/B58 provides a versatile wireless microphone solution for demanding live sound and installed audio applications.
Shure BETA 58A Supercardioid Dynamic Vocal Microphone
The Shure BETA 58A is a professional dynamic vocal microphone designed for lead singers, backing vocalists, and live sound reinforcement.
Known for its focused pickup and tailored vocal frequency response, the BETA 58A helps deliver vocal presence and clarity in challenging stage environments.
Supercardioid Pickup for Improved Vocal Isolation
The BETA 58A features a supercardioid polar pattern that provides tighter directional pickup than a conventional cardioid microphone.
This helps reduce unwanted sound arriving from the sides of the microphone, improving isolation from nearby instruments and other stage sources.
The focused pickup pattern can also help achieve greater gain before feedback when microphones and stage monitors are positioned correctly.
Tailored Frequency Response for Live Vocals
The BETA 58A offers a 50 Hz–16 kHz microphone frequency response, designed to provide strong vocal presence and detailed reproduction.
Its dynamic microphone construction makes it suitable for energetic live performances and professional speech applications.
Rugged Performance Construction
The BETA 58A is engineered for regular professional use, with durable construction suited to live performance environments.
Its microphone grille and internal design help support consistent vocal pickup during stage performances, rehearsals, and events.
Shure BLX2/B58 Handheld Wireless Transmitter
The included Shure BLX2/B58 handheld transmitter combines the BETA 58A microphone capsule with Shure BLX wireless transmission.
Its familiar handheld design allows singers, presenters, and worship leaders to move naturally throughout a stage or presentation area without a microphone cable.
Simple Group and Channel Configuration
The BLX2 features straightforward power and frequency group/channel controls.
After an available operating frequency has been selected on the receiver, the handheld transmitter can be manually configured to the matching group and channel settings.
An LED indicator provides convenient power and battery status information.
Up to 14 Hours of Battery Life
Powered by two AA batteries, the BLX2 provides up to 14 hours of operating time, depending on battery type and operating conditions.
This extended battery life is convenient for concerts, rehearsals, worship services, conferences, and professional events.
Shure BLX4R Single-Channel Rackmount Wireless Receiver
The Shure BLX4R is a rackmount wireless receiver designed for professional sound reinforcement systems and installed audio applications.
Unlike the standard BLX4 tabletop receiver, the BLX4R is designed for integration into equipment racks, making it suitable for touring systems, houses of worship, theaters, and corporate AV installations.
One-Touch QuickScan Frequency Selection
The BLX4R features Shure QuickScan frequency selection, which searches for an available operating frequency within the selected wireless frequency band.
Once an appropriate frequency has been selected, the BLX2/B58 transmitter is manually configured to match the receiver.
This simplifies wireless system setup in venues where other wireless microphones and RF equipment may be operating.
RF and Audio Level Monitoring
The BLX4R provides convenient receiver status information, including RF and audio level metering.
These features help sound technicians monitor wireless reception and incoming audio during system setup and operation.
Professional Audio Connections
The BLX4R includes balanced XLR and 1/4-inch audio outputs for connection to compatible mixing consoles, audio processors, and professional sound systems.
Its rackmount configuration helps keep wireless receiver equipment organized in permanent installations and portable production racks.
Rackmount Hardware Included
The BLX24R/B58 system includes rackmount hardware for installing the BLX4R receiver into a compatible equipment rack.
This makes it convenient for professional sound systems where organized equipment mounting is important.
Professional Shure BLX Analog UHF Wireless Performance
The Shure BLX24R/B58 operates using Shure BLX analog UHF wireless technology.
With an operating range of up to 300 feet (91 meters) under suitable line-of-sight conditions, the system provides freedom of movement for singers, presenters, and performers.
The BETA 58A microphone capsule has a frequency response of 50 Hz–16 kHz, while the BLX wireless system audio frequency response is specified as 50 Hz–15 kHz, depending on microphone type.
These are separate specifications for the microphone capsule and wireless system.
Multiple compatible BLX wireless systems can operate simultaneously, depending on frequency band selection and local RF conditions.
Actual wireless performance depends on interference, obstacles, equipment placement, and the operating environment.
